1.4. Testing a Standalone Unit
This section describes how to perform a G30 functionality test, whose purpose is to:
•Introduce the user to the G30
•Explain how to work with the G30 unit
•Describe how to evaluate basic G30 features
The test setup provides a wide platform through which a G30 unit can be evaluated. The
specific test procedure described below covers only a few of the G30’s many features. Using
this setup, you can perform several additional tests on the G30.
The test is performed using two modems, one of which is the G30. The modems communicate
with each other through a single computer, which also controls their operation.
The test requires knowledge about the operation of the G30 Developer’s Kit, terminal
applications and AT commands. Refer to relevant documentation for assistance.
To perform the test, you need the following:
•A G30 OEM cellular engine unit
•A G30 Developer's Kit
•A desktop or laptop computer, which includes:
–A free serial communications port (RS232)
–A connected and active line modem (internal or external)
–A terminal application (such as HyperTerminal)
1.4.1. Test Setup
To Setup the G30 Test
Follow this procedure (see following figure) to set up your equipment before performing the
test:
1. Verify that the computer you intend to use for the test is equipped with a working
line modem
You can use a second G30 unit instead of the line modem. When doing so, you must
repeat the setup procedure that follows for the additional G30.
2. Set up the G30 and the Developer Board as described in “Initial Setup” in
“ Developer Board and Interfaces Description” in the “G30 Developer’s Kit Guide”
3. Verify that the G30 has adequate reception from the local GSM network
4. Connect the Developer Board’s RS232 port to the computer’s serial port
5. Open a terminal application window (such as HyperTerminal) and configure it to operate
with the serial port occupied by the G30
6. Open a second terminal window and configure it to operate with the serial port occupied
by the line modem

1.4.2. Test Procedure
To Perform the G30 Test
Follow the procedure below to perform the G30 test:
1. Verify that the line modem is functioning and communicating with the computer by
entering the AT command at in the modem’s terminal window
This common AT command prompts a properly working modem to reply OK.
2. Verify that the G30 is functioning and communicating with the computer by performing
the following AT commands in the G30 terminal window:
•ati7 —prompts G30 identification
The G30 will reply G30 OEM Module.
•ati8 —prompts the G30 software version
3. Make a CSD call from the G30 to the line modem or the reverse using the atd and ata
commands in the appropriate window
4. Verify that a connection between the two modems is established
5. Select any file to transfer between the two modems
The file can be any existing file, or a new file created specifically for the test.
6. Send the file either from the G30, or to the G30, through the terminal application using
the terminal application’s send/receive file options
7. When the file transfer is complete, use the ath command in any of the terminal windows
to terminate the call
This step completes the test. You can now continue to perform additional tests using the
same setup, or change the setup as required.
